These type of seals with multiple spring is developed for universal applications. Their compact design permits their use in all types of centrifugal pumps. Through drive lugs the torque transmission from retainer shell to seal ring is done.
For easy installation and removal of the seal all components are held together by a snap ring. As all parts are interchangeable, conversion of series sv-l to sv-s can be made only by changing the seal ring and the secondary seal.
